I've been screenshotting others too the past couple years because I've always been curious on prices. I started doing this when my friend nostr:nprofile1qqsptssu6n4pvsjxth30na0llrnpa4u8x52cv4jtke9j5uvm77ldvvspzdmhxue69uhhwmm59e6hg7r09ehkuef00remkh started talking about his daily or weekly food orders. He always bought the same thing every day or week for work and would gradually see prices go up. So I started documenting it then too.
